dc.description.abstract

This study evaluates the effectiveness and impacts of USAID's IPM IL vegetable technology transfer subproject in Bangladesh. The effectiveness of the technology transfer is evaluated in four ways: IPM adoption rates and determinants of IPM adoption, measuring the impact of IPM adoption on vegetable yields, pest management costs, and the number of pesticide applications used, estimation of the economic impacts of IPM adoption and the technology transfer, and analysis of the relative efficiency of the various technology transfer methods used to transfer the IPM practices to farmers. Adoption determinants were identified using traditional and ordered probit regression analysis. Difference-in-difference models were used to identify the impacts of IPM adoption on yields, pest management costs, and the number of pesticide applications applied. Economic impacts of IPM technology adoption were measured using economic surplus analysis. Finally, to compare the relative efficiency of different technology transfer methods, adoption rates were identified for each transfer method and combined with the training cost per farmer to identify the cost per farmer adopting IPM practices.
The results from the adoption analysis suggest the number of years of agricultural experience of the household head, the number of IPM adopters known by the household, and learning agricultural information from media sources and/or farm training events such as field days significantly increase the likelihood of IPM adoption. The impacts of IPM adoption on vegetable yields, pest management costs, and the number of pesticide applications were non-significant for vegetable crops. Analysis of the cost efficiency of the different IPM technology transfer methods suggests that media sources such as television, radio, and newspapers have the lowest cost per farmer.
